Inclusion criteria
Inclusion criteria: (1) Patients who have given written consent to participate in the study. (2) Men and women at least 18 years of age at the time of consent. (3) Patients undergoing hemodialysis or hemodiafiltration three times a week on the day of the screening test conducted between 4 weeks and 1 week before the start of treatment. (4) Patients with pre-dialysis serum intact PTH greater than 121 pg/mL and pre-dialysis serum corrected calcium concentration greater than 8.4 mg/dL after the maximum dialysis day interval at the time of the screening test.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Weekly doses of vitamin D preparations every 4 weeks after the start of calcimimetics administration and the change from the start of calcimimetics administration. | — |
Secondary
| Measure | Time frame |
|---|---|
| Percentage of patients achieving management targets for corrected Ca, P, and intact PTH every 4 weeks after initiation of treatment. Time to achieve pre-dialysis serum intact PTH concentrations of 60-240 pg/mL, the control target. Percentage of patients with intact PTH 30% reduction every 4 weeks after initiation of treatment. | — |
